Hi everybody,

I wish to set up kind of a "learning path" (= "pedagogic" progression bar, like in http://www.dokeos.com/scorm_compliant_course_content.php)

/.../

...

Sorry for not being clear enough.

"learning path" is an acronym I've found while using Dokeos elearning platform, as an equivalent to a course i guess. For creating a course/learning path you assemble differents documents in a l.p.. When the alumni/trainee reads this course, he will be able what he have to read next after the fisrt doc, and so on. I've made a graphic capture of the webpage for showing what elements are making a learning path in the Dokeos vision : list of doc allready readen, docs to read, progression bar, plus the breadcrumb trail;

for lists of already learnt documents: you can make a list of chapters/sections/subsections somewhere on the page if you have enough place. If you would like to get the chapter/section/subsection name, you can get them with something like \getmarking[chapter] $>$ \getmarking[section] $>$ \getmarking[subsection] Perhaps some "if"s are missing to check if a section/subsection is defined, but someone else has to help you with it.

i don't want to put so much stuff in the pdfs made wit Context(apart putting an A4 text on an A3 page!) because i keep a printable A4 format for my courses, even i there interaction in it, for screen usage.

I'm not sure if I understood it properly, but if you need two different versions of your documents with the same content, but different layout, you can use modes (http://wiki.contextgarden.net/Modes).

...

So i wish to have only vertical progression bars + percentage in the inner margin. s-pre-01 "original" style show a bottom interaction bar filled with pagenumbers drawn as little rectangles. Maybe it's possible to draw a continuous bar with metapost, but for percentage ?

Ideally, i wish to have 2 progression bars : one for project progression and second for product prog.

How would you calculate the project progression? The example below calculates the percentage out of the number of pages in the current document.

Here's an example how to make an extremely simple and ugly progression bar at the bottom of the page. Take a look into the .mp file produced. You'll find many other variables thay you may use to position your progression bar properly.

\defineoverlay [ProgressBar A] [\useMPgraphic{ProgressBarA}] \setupbackgrounds [text] [background={ProgressBar A}]

\startuseMPgraphic{ProgressBarA} barW = 5cm; barH = .7cm;

StartPage; fill unitsquare xyscaled(barW*(PageNumber/NOfPages),barH) withcolor .625red; draw unitsquare xyscaled(barW,barH); label.rt(textext("$" & decimal(round(100*PageNumber/NOfPages)) & "\,\%$"), (barW,.5barH)); currentpicture := currentpicture shifted (LeftMarginWidth+LeftMarginDistance,2cm); StopPage; \stopuseMPgraphic

\starttext

first page\page second page\page third page

\stoptext

I would suggest you to get familiar with metapost/metafun ("learning metapost by doing", "the metapost manual", "metafun manual", ...) if you aren't yet. It's a simple and great programming/drawing language and you can do amazing things with it.

PS: just a note. Trying to execute the code written above under MikTeX (on the "old" ;) ConTeXt version, 2005.08.31) leads to distrous results and nothing worked as expected. It claims \loadfontfileoncetrue to be undefined command, it complains about file endings (it doesn't create .mpx files, so the label(textext ...) doesn't work) ... and so on. It may be that something is wrongly configured here, but I'm glad that I'm able to use the minimal ConTeXt distr. as an alternative when something fails under MikTeX.

Hi Mojca, Thanks a lot for your mp code, I got what i want but rightnow, I don't know how to use it exactly, maybe as follows attached (try to display a general progression thru advancement of each courses, and show on the same "pane" (inner margin)), list of each chapters. I'll try to cook a minimal but working example, as I got -- in a messy way -- almost everything for bring this new layout to life. -- Olivier TURLIER
